Kore
What Kore is
Kore is a Kotlin library for generating regular Minecraft datapacks from code. It runs during the build and outputs vanilla datapack files, so the server needs no Kore runtime or plugin. Typed game data helps catch typos in items, blocks, sounds, and commands during the build rather than at reload. The site lists more than 65 typed commands, over 50 JSON resource types, and over 80 generated registries. Kore supports datapack features such as commands, recipes, loot tables, advancements, and custom dimensions; Kotlin functions, loops, and variables can generate repeated content. When its typed DSL does not cover a command, function bodies can use raw command lines. Existing datapacks can be migrated incrementally alongside hand-written parts. Kore is available as a Maven Central dependency, and the maker recommends a JDK and Kotlin IDE. An optional Gradle plugin can build, link, and reload datapacks on save. A browser playground can generate a datapack ZIP. Kore does not currently ship bindings for mods or generate resource pack assets such as textures or models.
Who it suits
Kore suits Kotlin users building Minecraft datapacks who want typed game data and build-time generation. It may fit projects that can use a JDK and Kotlin IDE and do not need Kore-provided mod bindings or resource pack assets.
What it does well
- Generates vanilla datapacks without a server-side Kore plugin.
- Typed game data catches certain errors during builds.
- Supports incremental migration of existing datapacks.
- Browser playground can generate a datapack ZIP.
What to know first
- Does not ship bindings for mods.
- Does not generate resource pack assets.
Getting started
- Open the browser playground to try Kore and generate a datapack ZIP.
- For a local project, install a JDK and use a Kotlin IDE, as recommended by the maker.
- Add Kore as a Maven Central dependency.
- Optionally add the Gradle plugin to build, link, and reload the datapack when files are saved.
- Use the IntelliJ IDEA plugin or VS Code extension if they fit your editor setup.
Verdict
Kore adds typed, build-time datapack generation to Kotlin workflows while producing ordinary datapack files. Its current scope excludes resource pack assets and bundled mod bindings.
